Tomorrow, the 31st August, is a blue moon, in Pisces. A blue moon is so-called when there are two full moons in one month.
Am I reading too much into it that DC was born into a month in which there were no full moons at all, and passed away between the two full moons of this month? – Probably. I think we tend to look for meaning at such times as these, and perhaps there is none.
DC had great respect for the powers of the moon. He recognised the affect that it had on his body.
